  • 현대산업사회의 발전에 따라 신호처리 분야 중 디지털필터의 사용은 급격히 증가하고 있으며, 특히 디지털 영상처리, 디지털 음성처리, CATV 및 각종 통신 분야 등에서 카메라의 Detail processor, Y/C separator, Ghost제거 필터, 표준변환기(NTSC-PAL), Noise reducer 등으로 많이 사용되고 있다. 이러한 디지털필터에는 일반적으로 IIR(infinite impulse response)과 FIR(finite impulse response) 필터가 있으며, 본 논문에서는 구현이 용이하고 선형위상특성을 갖는 FIR 디지털필터를 설계하였다. FIR 디지털필터 설계에 있어서 통과대역의 차단주파수 부근에서 깁스(gibbs) 현상에 의해 생긴 리플을 완화하기 위해 window함수를 사용한다. 그러나, 기존의 window는 고정된 값으로 되어 있으므로 설계목적에 적합한 window함수를 선택함에 있어 다소 문제점이 있다. 따라서, 본 논문에서는 설계목적에 따라 서 융통성있게 선택이 가능한 파라메터를 부가한 변형된 Hanning window를 설계하였으며, 타당성을 입증하기 위해 디지털필터를 설계하여 기존의 Hamming, Hanning, Blackman, Kaiser window와 비교하였으며, 판단기준으로 peak side-lobe와 천이특성 등을 사용하였다.

  • The spiral form, which comes from the organic form of natural phenomenon such as growth of creatures, has been used as a factor of formative shape in various fields of art until now. In conjunction herewith, this study intends to discover and express the life force and the formative beauty of natural substances with the organic spiral forms into clothing design, using various creating methods and materials such as Korean traditional paper. The natural substances with the spiral structure, such as seashells, land snails, passion flower, curled flower, growing chart of plants, Impatiens textori was used as subjects of the designs. The seven pieces of work were completed with attempts to develop aesthetic forms through the presentation techniques and methods via restructuring process of simplification, partial transformation and consolidation. Through such process the conclusion of this study is as follows: First, the nature, with unlimited possibilities, could be subject of human formative activities, leading to the creative world of formative art for designers. Second, adaptation of the spiral organic forms of nature into the contemporary clothing designs proved the motif as a source of inspiration of diverse subject, in recognition with its innate formative beauty as well as external shape. Third, design expressions via restructuring process of simplification, partial transformation and consolidation with designer's subjective point of view were adequate for the creations of contemporary fashion designs. Fourth, the Korean traditional paper, as a fine material for various shape according to the handling method, could be used appropriately in the contemporary clothing designs, expressing our aesthetic senses. Fifth and finally, expansion of the realm of formative expression of clothing through the development of possibilities of expression in contemporary clothing would enhance the creative possibilities of clothing design as formative art. In conclusion, the expression of clothing design as formative art was developed on the emphasis of re-creation of natural objects of the organic spiral form. For the future study, the applications of spiral form into everyday clothing designs, consolidating artistic senses and practical senses, are expected as opportunity of proposing developmental possibilities of the contemporary clothing designs.

  • Stage costumes are characterized by the importance as a medium of total visual expression on a synthetic art and need to be designed more effectively. This study followed the stage costumes of the play 'Long long time ago whuo-ee whuoee' which participated in the China-Japan-Korea University Theatre Festival. By consisting of the framework of a Korean story that tells and expands the visual expression province by the access method of a producer, the unique costume in the play was created by the dyeing of the traditional hangi. First, the use of hanji in theater represents originality and a fresh variation with the formative beauty of stage costumes in accordance with hanji that conforms to the recreation of tradition. Second, the dip dyeing technique made it possible to express colors limitlessly and the airbrush dyeing technique along with dyeing twice could account for the weak points of the color. As a result, the color brought effect as expected. Third, the weak points were supported by a Jumchi technique that created the fibroid material tangled with stronger adhesion in the creation of a hangi costume. In addition, dyed hangi was attached to the outer fabric. It allowed the costume to have a unique texture that was both soft and tough. This enforced the visualization of the costume and durability to prevent possible damage by the performers. Forth, pieces of hanji were attached to the damaged parts of the costume after re-visiting the dress rehearsal. As a result, the stage costumes represented the shabby clothes that express the social class of the characters. A new understanding of the excellence of traditional hanji was found and confirmed the possibility of it as a material for stage costumes through the study.

  • 일반적으로, 영상 융합은 서로 다른 특징을 가지는 2개 이상의 영상을 이용하여 각 영상의 장점 및 특징을 모두 가지는 하나의 영상으로 재구성하는 것을 의미한다. 특히, 원격탐사 분야에서의 영상융합은 멀티스펙트럴 영상의 공간해상도를 향상시키는 것을 의미하며 이러한 이유로 인하여 Pan-sharpening 기술로도 불리어진다. 특히, 융합영상은 변화탐지, 영상 지도 제작, 도시 분석 등 다양한 분야에 적용 가능하기 때문에 중요성이 증대되고 있다. 그러나, 기존에 제안된 알고리즘들은 멀티스펙트럴 영상의 분광정보를 왜곡시키거나, 융합 영상의 공간해상도가 흑백영상의 공간해상도에 비하여 저하되는 문제를 지닌다. 이를 위해 본 논문에서는 멀티스펙트럴 영상의 분광 및 공간특성을 고려한 새로운 융합 방법론을 제안하였다. 본 알고리즘의 평가를 위해서 KOMPSAT-2, QuickBird 위성영상에 알고리즘을 적용을 하였으며, 기존의 영상융합 알고리즘에 비하여 공간적/분광적인 측면에서 모두 향상된 결과를 보임을 확인할 수 있었다.

  • The purpose of this study is to examine how he successfully connected his ideas of fashion design for art with the commerciality without a conflict about for 40 years. It is expected that this study will be a precedent in the aspect of the symmetry between artistry and commercialization in Issey Miyake's works. We will examine Issey Miyake's idea of fashion design and its development for the commercialization since 1970s that he started to give shape to his ideas in the fashion works to exactly commercialize in the market. 1. Re-creation of tradition(a piece of cloth): throughout the 1970s, Miyake continued to experiment with a variety of Eastern design elements. The elements of Japanese or oriental tradition made him to be at the very center of supreme of the world of fashion. He took advantages of his identity, and developed the tradition for mass produce. 2. Design for mass(Pleats Please): Miyake decided to make clothes for the people, not only for the top class of the society. This thought developed the designs for the mass, which were functional, universal for the modem buyer, and accessible to a wide market. He realized his ideal by the medium of pleats, which were made through industrial processes, while he tried variously the aspect of formative of the pleats in the collections. His designs concept is summarized by the industrial product design and anonymous design. 3. Innovation of manufacturing system(A-POC): Miyake in 1999 developed A-POC. A-POC is used modern computers in conjunction with traditional technology. A-POC does not make only a new cloth but also makes a new manufacturing system of clothes.

  • Currently the fashion industry is developing to create a novel culture due to the very sensitive and knowledge-oriented advancement of the IT industry. With fast turnover of information, consumers have come to have a more diverse desire for purchasing. Cubical expression techniques, which empathizes formativeness, can be a creative expression method adjusting into the trend of this era. Along with functional aspects of consumers, even in a textile manufacturing sector, new materials are required to meet sensitive and emotional aspects. Consumers' desire for new and creative designs and the development and adoption of new materials are essential to meet their emotions. The IT industry and fashion industry are forced to combine and a 3D apparel CAD system has been developed, enabling virtual clothing to be represented within a computer virtual space. All processes such as design, pattern creation, sewing and simulation are possible in 3D level. Digital clothing can shorten the production process time and is very effective in that it can reduce clothing waste generated during the sample production. This paper reviewed the works of Dutch designer, Iris van Herpen, who has developed formative designs. She tries to build, construct, and sculpt employing diversified materials other than soft textile materials, as shown in her series of fashion shows. The materials include films, 3D printed polymers, stiff and sheer organza, and artificial leather textiles. A few characteristics of her works have been selected in order to prepare patterns exhibiting the traits. The paper further focused on the physical features of the textile materials used to express similar techniques and its various forms were reviewed.

  • The cooperation between universities and industries is already one of the most important factors driving the national economy in the knowledge-based society of the 21st century represented by the Fourth Industrial Revolution. The Korean government has also been carrying out legal and institutional re-adjustments to promote industrial-university cooperation in line with demands for such changes in the times. However, despite this industry-academic cooperation system, there is still a significant mismatch between industrial demand and the university's workforce development system. By the way, there is a Cooperative Education(CO-OP) in Canada and the United States. It's an innovative link between the university and the industry. The reason is that the CO-OP program not only allows students to gain experience with their majors in the industrial field, but also plays a positive role in improving their specialty expertise. In particular, field information, ideas, and job insights that students acquire through CO-OP also serve as motivation for starting a business beyond employment after graduation. Furthermore, CO-OP experience is an important opportunity for future researchers to come up with commercialized research results that are not separated from the field sites The purpose of this study is to overcome the gap between industrial demand and the college manpower training system, and develop a Korean-style coaching program model as a growth engine for creative talent-building policies, represented by 'creation of start-ups and new industry.' In addition, this study suggested measures that can be applied in real universities. In addition, the study also highlighted that the introduction of CO-OP programs with field practices in Korea could also boost start-ups. Based on the Korean CO-OP program model, the curricula applicable to domestic universities consisted of two types : general and research-oriented university types.

  • Many areas of vegetation in the British uplands have reduced species diversity as a result of sheep overgrazing. It has been suggested that abandonment or re-wilding strategies might be used to reverse this. A likely first step would be the removal or reduction of grazing livestock from upland areas, with a presumption that this would lead to a recovery in species richness. However, we do not know if this would work, or the timescales involved. One of the important areas where more knowledge is needed is information on the size and composition of soil seedbanks as regeneration from zseed is a likely pathway of recovery. Here, we compared seedbanks in both grazed and ungrazed plots in five experiments at Moor House NNR in the northern Pennines; these sheep grazing exclusion experiments were started 52 and 63/64 years ago. Soil samples (n=10) were collected from both grazed and ungrazed plots in each experiment, and seed emergence counted in glasshouse trials. We detected only seeds of common species and very few dicotyledonous species. This suggests that the soil seedbank is unlikely to be a reliable source of the less common species for ecological restoration in these upland communities, suggesting an extinction debt. Therefore, seed addition and the creation of suitable safe-sites for germination may be needed in conjunction with grazing controls to allow the establishment of plants that will increase the species richness of the vegetation. However, this interventionist restoration approach remains to be tested.

  • In history based parametric CAD modeling systems, persistent identification of the topological entities after design modification is mandatory to keep the design intent by recording model creation history and modification history. Persistent identification of geometric and topological entities is necessary in the product design phase as well as in the re-evaluation stage. For the identification, entities should be named first according to the methodology which will be applicable for all the entities unconditionally. After successive feature operations on a part body, topology based persistent identification mechanism generates ambiguity problem that usually stems from topology splitting and topology merging. Solving the ambiguity problem needs a complex method which is a combination of topology and geometry. Topology is used to assign the basic name to the entities. And geometry is used for the ambiguity solving between the entities. In the macro parametrics approach of iCAD lab of KAIST a topology based persistent identification mechanism is applied which will solve the ambiguity problem arising from topology splitting and also in case of topology merging. Here, a method is proposed where no geometry comparison is necessary for topology merging. The present research is focused on the enhancement of the persistent identification schema for the support of ambiguity problem especially of topology splitting problem and topology merging problem. It also focused on basic naming of pattern features.
